1. you have to replace a watch and as soon as you put it on you want to go and run.
2. You worry about how it will look with what you race in or the color of your bike.
3. You try and hang on to a watch that has been acting screwy for a while changing times and functions at random just so you can keep your HRM. My watch would go up four hours, down a few, up some morem, and then switch back to the right time. Also when you would push the mode button once it would recognize it as pushing the button X number of times a cycle through over and over... quite frustrating.
I felt a little bit addicted this morning though when I put my new ironman watch after buying it at 6:30 before work. I wanted to do a tri or something so bad. Kinda weird. I will def. have a good time training this afternoon.
